To ali! whom I? may concern:

Be it known that we, WILLIAM S. PARKER., DANIEL H. BLooD, and Gris F. Towne, citizens of the United States of America, residing at Laingsbnrg, in the county of Shiawassee and State oi' Michigan, have invented certain neor sind nsefnl Improvements in Shaking Bolts, of which the following is aspeciiicetion, reference being` had therein to the accompanying drawings.

The object of this improvement is the construction of a machine that is adopted to ralpidly and efficiently bolt door through o. dat sieve. These results are attained by the niechanisni illustrated in the drawings, forming part hereof, in vwhich the saine letters of reference denote the saine parts in the dilierent views.

Figure l is a side elevation, with the parts broken away, representing a shaking bolt einloodying the features of my improvement. Fig. 2 is a front elevation with parts removed that are folly shown in other iignres. Fig. 3 is en end elevation, partly in section and with parts removed and broken away. Fig. 4 is an inverted longitudinal section taken on the line x .fc of Fig. l, more fully showingsT the construction and relation of theparts. Fig. 5 isa perspective representation of one of the brackets. Fig. 6 is a perspective representation of a. section of one of the rack-bars iixed to side walls. is a iront elevation of one ofthe sproeketwvheels on brush-shaft. Fig. 8 is a. perspective representation of a portion of one of the sproclictchains. Fig. 9 is a perspective representation of one oi' the spring-hangers. Figs. l@ and il are perspective representations of the blocks freni which the springhangers are suspended.

A A. A2 A* ABA nnindicate theinclosing and supporting frame, of which A A AL a: a are the side Walls. A* A5 are upright and longitudinal franiebeains, and A A are the end walls. The parts A A of the side Wells are suitably connected to the upright beams Af ont of line with the side Woll parte, A A2, as fully shown in 3, and are connected with such parts by ineens of strips a ce, for preventing the openings in the sidewalls, that would otherwise occur from the position of the parts A The parts A ere each provided with e slot, ns shown at o in Fig. l, for a purpose hereinafter set forth.

The frame-Walls et both sides of the inw chine may be provided with Windows, as shown at a?.

B is a spout for introducing into the niachine the material to be bolted.

C is an inclined board,alon 1 which the door moves from the spout to the bolt. D is an oppositely-inclined board, with the lower edge adjacent to the boa-rd C, and adapted to spread the material passing` along' the hoard C- to the` bolt. The boards C and D are secured to the Wall parts A A by any suitable means.

E E represent blocks lined either to the wall ports A A or to the longitndi nal framebeanis A5.

E E are spring-steel hangers suspended from the blocks E E, all which are rounded at their inner ends, as shown in Figs. l2 end 18, which correspond in size with and are setinto eyes formed at the opper ends of the hangers E E, as shown in Fig. ll, which are also provided with eyes at their lower ends, through which they are connected to the bolt-frame F by means of pins f, projecting therefrom beyond the outer sides of thewall parts e. A.

The Wall parts A are ont awa-y, as shown at ci ce?, Fig. 1, for the purpose of connecting the spring-hangers E E with the pins f, projecting from the bolt-frame F, and for the purpose of clearing the reciprocating motion of the springhangers hereinafter explained.

The spring-hangers lj E are of the saine length, but are connected to the bolt-frame F, inanienner to suspend the saniein an inclined position, by means of the pins Jinhich project through the lower eyes of the springhangers and which are xed to the frameF at different distances from the top of the saine, substantially as shown in Fig. 1.

The under part of the boit-frame F is provided at each side with eyepietes adjacent to itsfront ends, as shown at if, Figi, to which are pivotally connected rods l1, which are also suitably connected to yokes h of eccentrics ha on the driving-shaft H, jonrnaled to brackets A3,(more fully shown in Fig.5,) and which are fixed to the inclosing-franie in the ordinary manner by bolts, as shown.

H is e drivingpuiley on shaft H, Which is provided at its end opposite to the pulley H with a connterpnlley, J.

K E represent ordinary sprocket-Wheels fixed to both ends of shafts L L, located at opposite ends of the inclosing-frame. The shaft L has bearings in integral projections of the brackets A3 at the front end of the machine, and the shaft L is supported by suitable brackets fixed to the rear end of the frame, as indicated at A7 in Fig. l.

K2 represent sprocket-chains arranged to operate in connection with sprocket-wheels K K at both sides of the inclosing-frame. The chains K2 are provided with two opposite series of links having arms K3 and interposed portions consisting of plain links without arms, for a purpose hereinafter explained. The peculiar construction of these sprocket-chains is more fully illustrated in Fig. l0.

RR represent sprocket-wheels having distinct series of teeth, each of which distinct series of teeth have positions preferably corresponding to the spaces between the opposite series of teeth. These sprocket-wheels R R are suitably secured to opposite ends of a transverse shaft, i', having bearings in and supported by the slots a'in the wall parts A, as fully shown in Fig. 3, The shaft i' is adapted by shoulders 1" fiat each side of the wall parts A,to strictly maintain its transverse relation to the other parts of the machine.

R is a fine steel wire or bristle brush fixed to the sha-ft r. The bristles of the brush R are to be of sufficient length to engage positively with the texture of the sieve G in the lower part of the bolt-frame. The sieve G is suitably secured to thelower partofthe bolt-frame.

N is a pulleyiixed to ashaft, N', having bearings in and supported by integral projections or arms of the brackets A.

P is agear-wheel fixed to a shaft, P', having bearings in and supported by integral proj ections or arms of the brackets A3,and N2, (shown in Fig. 2,) is a pinion on the shaft N,arranged to mesh with gear-wheel P on shaft I, which is provided at one end with a pulley, P2. The shaft P is also provided with miter-gears p p, arranged to drive ordinary discharge-conveyers, (not shown,) hy means of corresponding gears, pp, fixed to the conveyer-shafts.

K is a pulley fixed to the shaft L in line with the pulley P" on shaft 1?.

The shaft N will be putin motion by connection of the pulley N with the pulley H', through a belt. (Not shown.)

The shaft L will be putin motion by connection of the pulley K* on said shaft with the pulley J on shaft H, through a belt. (Not shown.)

By reason of the socket-wheels on the shaft L, motion of the latter will give c orresponding movements to the sprocket-chains connecting therewith.

When the machine is put in motion, the bolt-frame F will vibrate more or less rapidly by reason of the hangers E E and its connection with the eccentries on the shaft H,through the rods h. The sprocket-chains K2 will give rotary motion to the brush R by the arms of the links K3 being brought in contact with the projections of the sprocket-wheels R at each end of the brush-shaft r. The sprocketchains will move in the direction of the arrows shown in Fig. l, and in addition to giving rotary motion to the brush R will cause the projections of the inner division of the sprocket-wheels R to consecutively enter the divisions of adjacent corresponding racks, R, suitably secured to the wall parts A', in positions parallel with the slots a', and the shaft of the brush R will thus be made to move along the slotsa and engage with the entire texture of the sieve G. XVhen the links having the arms K3 pass the wheels R the gravity of the brush R will cause it to roll down the inclined slots a and racks R2 to the front ends ofthe same, after which the opposite series of link-arms K3 will engage the projections of the wheels R, and repeat the movement of the brush R described, and thus cause its alternating motion to the opposite ends of the slots a during the operation of the machine, .and the sieve will be prevented from clogging by the continual Contact of the brush therewith, and the line flour will thus be rapidly and effectively separated from the chop, which will be worked toward and over the highest end j of the bolt-frame into a suitable receptacle, and thence removed in the ordinary manner.

Having explained the features of our improvement, what we claim as new, and desire to secure by Letters Patent, is

l. In a tlour-bolting machine, the combination of the inclined bolt-frame, a sieve, the inclosing-frame provided with inclined slots in its sides,the rack-bars secured to the inclosingframe adjacent to its inclined slots and parallel therewith, the sprocket-chains provided at intervals with a series of links having arms, as Shown,the means for supporting and operati ng the'same, and the brush provided with gearwheels having distinct series of teeth for meshing respectively with the racks adjacent to the slots in the side walls and for engaging with and being operated by the sprocket chain arms, said brush being arranged to roll down the inclined slots after the passage of thelinkarms, substantially as specied,:t'orthe purpose set forth.

v2. In a ilour-bolting machine, the sprocketchains provided at intervals with arms, as shown, and the means for supporting andvoperating the sprocket-chains, in combination with the brush provided with sprocket-wheels, the racks fixed to the side walls, and the boltframe and sieve, substantially as specified, for the purpose set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
